Social objectivity is a peculiar type of objectivity to be
distinguished from the objectivity of physical objects, whose hardness
also (in a certain sense) vanishes into thin air when you pause and
think about its deeper structures. Ask the physicists. Social
objectivity can unravel unannounced when people's collective beliefs
in the permanence of said social structures shift. And the shifts in
collective beliefs can be precipitated by tiny, molecular changes,
where even the choices made by a single individual can pack a big
punch. In turn, that doesn't mean that the choices of individuals are
the only or even the essential causes of these ideological shifts,
since the shifts are *always* prepared by long, gradual social
processes, sometimes unnoticed, processes that (again) partly at least
embody or objectify the designs of people -- e.g. organizers, organic
intellectuals, even leftists having endless discussions and conducting
sandbox politics.
Marx wrote:
"Once the inner connection of things has been exposed, the theoretical
belief in the eternal necessity of the existing conditions collapses,
even before the collapse happens in practice."
This is a very powerful idea. I call it the Marxist epiphany, from
epi (outside) and phaneia (appearance), the inside of reality
revealing itself outwardly. Very Hegelian. We still need to
distinguish between (1) the collapse of the belief in the eternal
necessity of the existing conditions and (2) the collapse of the
actual existing conditions. Because they are not one and the same
thing.
